Learn How to Promote: Pawn Promotion
This chess endgame is a classic example of how an advanced pawn can decide the game instantly. Even when one side has major material, a passed pawn on the seventh or second rank can create a direct tactical threat that overrides everything else. Here, the key idea is that promotion is not just about winning a queen later — it can also be a forcing move that delivers immediate mate and ends the game on the spot.
